We study the recurring jets near AR11176 during the period 2011 March 31 17:00 UT to April 1 05:00 UT using observations from the Atmospheric Imaging Assembly (AIA) on board Solar Dynamics Observatory (SDO). Mini-filaments (mini-filament1 & 2) are found at the base of these recurring jets where mini-filament1 shows the partial signature of eruption in case of Jet1–3. However, the mini-filament2 shows a complete eruption driving a full blow-out jet (Jet4). The eruption of mini-filament2 triggers C-class flare and Jet4 eruption. The eruption of Jet4 triggers a coronal mass ejection (CME). The plane-of-sky velocity of recurring jets (Jet1–4) results in 160 km s −1 , 106 km s −1 , 151 km s −1 and 369 km s −1 . The estimated velocity of CME is 636 km s −1 . The continuous magnetic flux cancellation is observed at the base of the jet productive region which could be the cause of the eruption of mini-filaments and recurring jets. In the former case, the mini-filament1 shows partial eruption and first three jets (Jet1–3) are produced, but the rate of cancellation was rather low. However, in the latter case, mini-filament2 fully erupts (perhaps because of a higher cancellation rate), and this triggers a C-class flare and a CME-productive jet. At the base of first three jets (Jet1–3), the mini-filament1 causes to push the overlying dynamic complex thin loops resulting in the reconnection and drives the jet (Jet1–3) eruptions. The formation of the plasma blobs are observed during the eruption of the first jet (Jet1).

活动区域附近的 CME 生产性和非生产性重复喷气机 AR11176

我们使用太阳动力学天文台 (SDO) 上大气成像组件 (AIA) 的观测结果研究了 2011 年 3 月 31 日 17:00 UT 至 4 月 1 日 05:00 UT 期间 AR11176 附近反复出现的喷流。在这些反复喷流的底部发现了微型细丝(微型细丝 1 和 2),其中微型细丝 1 显示了 Jet1-3 喷发的部分特征。然而,迷你细丝 2 显示了一个完整的喷发,驱动了一个完全喷出的射流 (Jet4)。mini-filament2的喷发引发C级耀斑和Jet4喷发。Jet4 的喷发触发了日冕物质抛射(CME)。重复射流 (Jet1-4) 的天空平面速度导致 160 km s -1 、106 km s -1 、151 km s -1 和 369 km s -1 。CME 的估计速度为 636 km s -1 。在射流生产区的底部观察到连续的磁通量抵消,这可能是微型细丝和重复射流喷发的原因。在前一种情况下,微型细丝 1 显示部分喷发并产生前三个喷流(Jet1-3),但取消率相当低。然而,在后一种情况下,mini-filament2 完全喷发(可能是因为更高的取消率),这会触发 C 级耀斑和 CME 生产喷气机。在前三个喷流 (Jet1-3) 的底部,微型细丝 1 推动上覆的动态复杂薄环,导致重新连接并驱动喷流 (Jet1-3) 喷发。在第一次喷射 (Jet1) 喷发期间观察到等离子体团的形成。在前一种情况下,微型细丝 1 显示部分喷发并产生前三个喷流(Jet1-3),但取消率相当低。然而,在后一种情况下,mini-filament2 完全喷发(可能是因为更高的取消率),这会触发 C 级耀斑和 CME 生产喷气机。在前三个喷流 (Jet1-3) 的底部,微型细丝 1 推动上覆的动态复杂薄环,导致重新连接并驱动喷流 (Jet1-3) 喷发。在第一次喷射 (Jet1) 喷发期间观察到等离子体团的形成。在前一种情况下,微型细丝 1 显示部分喷发并产生前三个喷流(Jet1-3),但取消率相当低。然而,在后一种情况下,mini-filament2 完全喷发(可能是因为更高的取消率),这会触发 C 级耀斑和 CME 生产喷气机。在前三个喷流 (Jet1-3) 的底部,微型细丝 1 推动上覆的动态复杂薄环,导致重新连接并驱动喷流 (Jet1-3) 喷发。在第一次喷射 (Jet1) 喷发期间观察到等离子体团的形成。这会触发 C 级耀斑和 CME 生产型喷气机。在前三个喷流 (Jet1-3) 的底部,微型细丝 1 推动上覆的动态复杂薄环,导致重新连接并驱动喷流 (Jet1-3) 喷发。在第一次喷射 (Jet1) 喷发期间观察到等离子体团的形成。这会触发 C 级耀斑和 CME 生产型喷气机。在前三个喷流 (Jet1-3) 的底部,微型细丝 1 推动上覆的动态复杂薄环,导致重新连接并驱动喷流 (Jet1-3) 喷发。在第一次喷射 (Jet1) 喷发期间观察到等离子体团的形成。
